$8.99

Your expert strategist for building, listing, and scaling high-profit Halloween printable bundles on Etsy.

🔁 Model Migration Checker

by JustHandled Labs

$6/mo

Find the model-version coupling that breaks when you swap LLMs. Flags hardcoded model names and versions, deprecated or renamed parameters (the max_tokens to max_completion_tokens class of change), hardcoded token and context-window limits, response-format parsing tied to one model's output, tool-schema format coupling between providers, and hardcoded per-token cost constants. The patterns load from an editable model-rules table you update as new models ship.

⚖️ License Picker

by JustHandled Labs

Free

Generate a ready-to-use LICENSE file for your repo. Pick from MIT, Apache-2.0, GPL-3.0, MPL-2.0, BSD-2-Clause, BSD-3-Clause, or The Unlicense, fill in your name and year, and get the canonical license text. Prints to the screen by default and writes a LICENSE file only when you ask.

⚡ Perf Budget Auditor

by JustHandled Labs

$12

Audit your frontend build against a performance budget and catch size regressions before you ship. Flags total bundle over budget, initial bundle over budget, individual chunks over a threshold, oversized image assets, source maps shipped to production, and large unminified JavaScript. Reads a webpack or Vite-style stats.json plus a perf-budget.json you control.

🔐 Email Auth Deliverability Doctor

by JustHandled Labs

$12

Audit your SPF, DKIM, and DMARC records for the misconfigurations that get mail rejected or sent to spam. Flags a missing DMARC record or p=none, missing rua reporting, a missing or duplicated SPF record, SPF over the 10-lookup limit, permissive +all/?all, a missing DKIM selector, and SPF/DKIM domain-alignment mismatches. Paste a DNS zone file or dig/nslookup output.

📦 Package Supply Chain Sentinel

by JustHandled Labs

$19

Vet dependency changes for supply-chain risk before you install, commit, or release. Scans package and lockfile diffs for install-time lifecycle scripts, non-registry sources, suspicious download commands, typosquatting, and floating versions, across npm, pnpm, yarn, pip, uv, and poetry. Flags what to review with evidence. No install required.

🐳 Docker Compose Stack Doctor

by JustHandled Labs

$15

Diagnose why your Docker Compose stack won't come up: port conflicts, bad or missing env vars, absent healthchecks, volume and permission issues, depends_on that doesn't wait for readiness, networking gaps, platform mismatches, and databases that aren't ready. Reads your docker-compose.yml and logs and ranks the blockers with fixes.

🖼️ Open Graph Social Card Auditor

by JustHandled Labs

$12

Catch the Open Graph and Twitter Card problems that make a shared link preview blank or broken. Flags missing og:title, og:image, og:description, og:url, or twitter:card, a relative og:image URL (crawlers need an absolute one), an SVG og:image (no platform renders it), and image dimensions that miss the 1200x630 standard. Reads your HTML or pasted head markup; it does not fetch the page or refresh a platform's cache.

📖 Voice Bible

by JustHandled Labs

$13

Audit a draft against your own voice spec and flag every line that breaks your house style. Checks banned words and phrases, em-dashes (when your spec bans them), sentences over your word-count cap, off-spec terms that have a preferred replacement, missing contractions, and forbidden clichés. Config-driven by a voice-spec.json you control, with a sensible default spec if you don't supply one.
